Other aerosols can host chemical reactions that damage the ozone layer.

其他气溶胶可以主导伤害化学反应。

High up in the atmosphere, ultraviolet radiation transformed oxygen into ozone and gave Earth a vital shield — the ozone layer.

在大气高处，紫外线辐射将气转化，地球提供了一个至关重要屏障——。

A second important area is monitoring the size of the hole in the ozone layer above Antarctica, since this is an indicator of global ultra-violet radiation levels.

第二个重要地方是检查南极洲上空空洞大小，因它标志着全球紫外线辐射水平。

In regards to humans and animals - even with our ozone layer, we can't stare at the Sun for more than 60 seconds without risking blindness - with a 100% decrease of ozone, blindness could also set in immediately.

对于人类和动物来说——在有情况下，我们盯着太阳超过60秒也会有失明危险——因此一旦含量100%下降，我们也会立即失明。

It's linked to global warming, acid rain, effects on wildlife, depletion of the ozone layer.

空气污染和全球变暖、酸雨、野生动物保护、耗竭这些问题息息相关。

Right. So in this headline, it's saying that if nothing changes, if everything carries on the way that it is now, then the Earth's ozone layer — this protective shield — will have recovered by 2066.

没错。因此，在这个标题中，它说是，如果什么都不改变，如果一切都照现在这样进行下去，那么地球——这个保护——将在 2066 年恢复。

After all, nothing can fry us more and better than cosmic radiation and this will happen because the ozone layer will also disappear.

毕竟，没有什么比宇宙辐射更能把我们烤焦了，这将会发生，因也会消失。

The disappearing ozone layer causes increased temperatures around the world, triggering cyclones, tsunamis and hurricanes.

消失导致全球气温升高，引发龙卷风，海啸和飓风。

A chemical that helped to create a hole in the ozone layer is reappearing.

一种导致空洞化学物质重新出现。

The ozone layer, our protection against the sun's UV rays, is made of oxygen.

气组成使人免受紫外线伤害。

It goes up every morning at 11 o'clock and measures air temperature and the density of the ozone layer to an altitude of up to 30 kilometers.

它每天早晨11点上升，并测量高达30公里气温和密度。

These do not harm the ozone layer and are more energy efficient.

它们不会损害，而且更节能。

The ozone layer is becoming very thin and letting too many dangerous rays reach us.

变薄，人类会遭到许多危险射线侵扰。

An international report says human action to save the ozone layer appears to have worked.

一份国际报告称，人类拯救行动似乎奏效了。

It would be enough to totally destroy the Earth's ozone layer.

这足以彻底摧毁地球。

A new United Nations report says the Earth's ozone layer appears to be healing.

联合国一份新报告显示，地球似乎正在愈合。

This pays great dividends for everyone as it also serves to protect the ozone layer.

这对每个人都有好处，因它还可以保护。

But scientists later realized that these compounds can release chlorine that reacts with ozone molecules in the atmosphere, depleting the Earth's ozone layer, which protects us from UV radiation from the sun.

但科学家后来意识到，这些化合物可以释放氯，与大气中分子发生反应，从而消耗地球，而保护我们免受太阳紫外线辐射。

The Earth's ozone layer is expected to recover within 40 years and will be protected by the phasing out of nearly 99% of ozone-depleting substances, a UN-backed panel of experts said in a report Monday.

当地时间周一，一个由联合国支持专家组发布报告表示有望在 40 年内恢复，已经通过逐步淘汰近 99% 消耗物质，而得到了保护。

There are UN-sponsored international laws to deal with issues like climate change, ozone layer depletion, protection of biological diversity, protection of international watercourses, protection of endangered species, regulation on persistent organic pollutants.

联合国发起国际法处理气候变化、损耗、保护生物多样性、保护国际水道、保护濒危物种、管制持久性有机污染物等问题。
